As the top product of the water purifier, the pure water machine has the most thorough and safe water purification effect; when the pure water machine is working, the water flows through the RO reverse osmosis membrane to filter out bacteria, viruses, radioactive substances and heavy metals and organic substances contained in the water. Wait. However, the filtration efficiency of the pure water machine is relatively small, which cannot meet the requirements of water intake at any time. Therefore, a pressure storage bucket is usually installed in the water purifier; when the user does not take water. The pure water machine works at the same time, and the pure water produced is first stored in the pressure tank. When the user needs water, it is directly outputted from the pressure tank, so that it is not necessary to wait for the time for filtering the water.

Here, the structure of the pressure water storage tank which is generally used is as shown in Fig. 1, and the pressure water storage tank is partitioned by the rubber film 1 into the water storage portion 2 located above and the air bag 3 located below.

The principle of the water storage cycle is that the airbag 3 is first inflated, and the pure water mechanism squeezes the airbag 3 when the water is supplied to the water storage unit 2, so that the influent water is subjected to the pressure in the opposite direction of the airbag 3, and when the water inlet continues to this pressure When the water is equal to the inlet water, the water inlet stops; when used for water intake, the outward pressure generated by the expansion of the squeezed airbag 3 causes the water to flow outward. When the expansion pressure is equal to the atmospheric pressure, the water stops; The step of copying the water into the water squeezes the air bag 3, thereby achieving continuous circulation of the influent and effluent as a whole.

Detailed ways

The implementation, functional features, and advantages of the present invention will be further described in conjunction with the embodiments. It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

The invention provides a pressure water storage bucket with a sterilizing function, which is mainly used for, but not limited to, a pure water machine. As shown in FIG. 2-3, the first necessary functional design of the foundation has a rubber touch 10 separated to be located above. The water storage unit 20 and the air bag 30 located below are provided with a water inlet and outlet 40 in the water storage unit 20, and an air inlet 50 in the air bag 30. The valve body 60 is further provided on the top of the water storage unit 20.

Further, the present invention is based on the purpose of sterilization, and an ultraviolet sterilization assembly is disposed in the pressure storage tank, and the ultraviolet sterilization assembly includes an ultraviolet light source 61 installed in a space inside the valve body 60, and at the same time, in order to make the ultraviolet light source of the ultraviolet light source 61 The water storage unit 20 is sterilized, and an optical fiber 62 is further provided on the valve body 60. The optical fiber 62 has a probe end and an output end. The probe end is used for collecting the deep ultraviolet light emitted by the ultraviolet light source 61, and is outputted from the output end after being transmitted through the optical fiber 62. Therefore, in the present invention, the probe end of the optical fiber 62 and the ultraviolet light source are used. 61 is relatively disposed to facilitate deep ultraviolet light collection, and the output end of the optical fiber 62 is disposed in the water storage portion 20 to perform ultraviolet irradiation on the water storage portion 20.

According to the above structural design of the present invention, by installing the ultraviolet light source 61 in the valve body 60, the opening in the pressure tank can be eliminated, and the airtightness and sealing property in the pressure tank can be ensured on the one hand, and the production processing and the like are reduced on the other hand. The instability, as well as the disadvantages of increased hours and costs. At the same time, the deep ultraviolet light is introduced into the water storage portion 20 through the optical fiber 62, and the normal ultraviolet light irradiation under high pressure is installed, and the influence of the water storage level and the pressure change on the deep ultraviolet light is not caused. Based on the operational requirements of the optical fiber 62 of the present invention, an optical grade of Teflon or hexafluoropropylene (FEP) of the optical fiber 62 can be used, and the diameter is controlled from 25 μm to 100 μm.

Further, as can be seen from FIG. 2, the number of the ultraviolet light sources 61 may be plural, and is installed at the side wall and the bottom of the valve body 60, and the ultraviolet light source 61 at the bottom is more convenient for light output with the water storage portion 20, and The ultraviolet light source 61 on the side wall can emit a deep light to illuminate the lateral duct space in the valve body 60 when the valve body 60 is closed, thereby suppressing or even killing bacteria inside, and further improving the antibacterial ability of the pressure tank.

At the same time, based on the necessity of the function implementation, the entire pressure storage bucket also provides a power source for the illumination of the ultraviolet light source 61. In Fig. 2, all of the ultraviolet light source 61 is electrically connected to the power source externally provided by the pressure storage tank through the wires 611. In the present invention, the internal space of the valve body 60 is limited and the convenience of installation and wiring is insufficient. Therefore, it can be seen that the power source is not disposed inside the valve body 60, and the technician can set the power source to an external convenient position according to convenience. Alternatively, the pressure storage tank itself does not provide the power source, and the main power supply device of the pure water machine is directly borrowed, and the ultraviolet light source 61 is electrically connected to the wire 611.

In the present invention, in order to increase the amount of light and the sterilizing intensity of the optical fiber 62, an ultraviolet lens 63 is further disposed between the optical fiber 62 and the ultraviolet light source 61, and the light emitted from the ultraviolet light source 61 is collected and collected by the probe end of the optical fiber 62. This can increase the amount of light collected; as can be seen from the above, the ultraviolet lens 63 is a convex lens, preferably a lenticular lens. At the same time, according to the object of the present invention, the ultraviolet lens 63 is disposed in the optical axis of the ultraviolet lens 61 and is placed close to the optical lens of the ultraviolet lens 61, so that the light collection amount is improved when the setting is performed. Good, and more conducive to light into the probe of the fiber 62.

In the above embodiment, in order to enhance the effect of the optical fiber 62 probe on the light collection of the ultraviolet light source 61, the ultraviolet light source 61 is further provided with a reflector cup 64. The reflector 64 is used to condense the light emitted by the ultraviolet light source 61 located inside thereof, and reduce astigmatism and glare, thereby effectively reducing the light loss of the ultraviolet light emitted by the light source and improving the utilization of the ultraviolet light. From the lighting effect of the present invention, the arrangement of the reflector cup 64 is preferably disposed toward the ultraviolet lens 63 in the open direction, and further, the central axis of the reflector cup 64 may be disposed in the optical axis direction of the ultraviolet lens 63 to coincide with the optical axis. This ensures that the concentrated light is maximally focused by the ultraviolet lens 63.

Based on the above arrangement of the reflector cup 64 and the ultraviolet lens 63, in order to improve the mounting manner of the component, a base 65 may be disposed in the valve body 60 for mounting and fixing the reflector 64 and the ultraviolet lens. 63. The probe end of the optical fiber 62 can ensure stable installation and operation of these components on the one hand, and the base 65 and the objects fixedly mounted on the base 65 can be used as an entire detachable module on the other hand. It is convenient for module production, assembly and post-maintenance maintenance of the entire product. Of course, the fixed connection manner of the pedestal 65 with the reflector cup 64, the ultraviolet lens 63, and the optical fiber 62 can be respectively provided with a fixed connection structure in which these components are fitted to the outer shape or to a specific portion. Of course, when the optical fiber 62 is installed, it is required to penetrate the bottom wall of the valve body 60 to insert the output end into the water storage portion 20. In the implementation, a socket for the optical fiber 62 to pass through may be disposed on the bottom wall of the valve body 60. However, after the optical fiber 62 is installed, the gap of the jack can be sealed by a sealing means to prevent water in the water storage portion 20 from overflowing into the valve body 60 from the gap of the socket.

Further, since the deep ultraviolet light outputted from the output end of the optical fiber 62 is irradiated along the light outgoing direction of the optical fiber 62, the illumination angle is relatively small, so that an astigmatic lens (not shown) can be disposed at the output end of the optical fiber 62. The angle of the outgoing light emitted from the output end of the optical fiber 62 is spread to a larger extent, and the irradiation area inside the water storage portion 20 is raised to better sterilize. Of course, based on the requirements of the present invention, the astigmatic lens can be a double concave mirror, and its arrangement can be set directly in conjunction with the output end of the optical fiber 62, and the double concave mirror can also be arranged as an optical axis and an optical fiber 62 output. The output angles of the ends coincide, so that the diffusion of light works best. At the same time, based on the amount of light emitted from the inside of the water storage portion 20 and the irradiation width of the lift fiber 62, a plurality of light leakage holes (not shown) for facilitating light emission may be provided on the optical fiber 62. Through the light leakage hole, more ways of light emission can be added, so that the inside of the water storage portion 20 can be more completely illuminated by ultraviolet light.

Of course, since the emitted light is not irradiated at a full angle, in order to form a full illumination of the light inside the water storage portion 20, the dead angle of the ultraviolet light is eliminated; further, the inner side wall of the water storage portion 20 is designed as a diffuse reflection side wall, and the diffuse reflection side The wall allows the internal space of the water storage portion 20 to form a uniform light field. The diffuse reflection sidewall can be realized by attaching a high diffuse reflection film on the sidewall, or the inner wall of the water storage portion 20 can be made of a suitable material and processed to have a diffuse reflection on the sidewall thereof. The structure allows the sidewall itself to have a diffuse reflection function.

Further, based on the above embodiments, based on the installation convenience of the pressure storage water tank in the pure water machine product, a positioning and positioning positioning structure may be disposed on the outer side wall of the water storage portion 20, and the positioning structure may be stored. The positioning pin 21 disposed on the outer side wall of the water portion 20 is disposed on the water purifier corresponding to the positioning pin 21; or the positioning pin 21 is disposed on the water purifier, and then the water storage portion 20 A matching positioning socket is provided on the outer side wall.

Based on the above embodiment of the pressure storage bucket, the present invention further provides a water purifier comprising the above pressure storage bucket having a sterilization function. In the installation and use, the inlet and outlet of the pure water machine can be connected to the inlet and outlet 40 of the water storage unit 20 in the pressure storage tank of the sterilization function of the present invention. After being turned on, the air bag 30 is first inflated, and the pure water mechanism water presses the air bag 30 when the water storage unit 20 enters the water, so that the water inlet is subjected to the pressure in the opposite direction of the air bag 30, and when the water enters until the pressure is equal to the water inlet power When the water is used for water withdrawal, the outward pressure generated by the expansion of the squeezed airbag 30 causes the water to flow outward. When the expansion pressure is equal to the atmospheric pressure, the water discharge stops; at this time, the water can be re-reproduced. The step of squeezing the air bag 30 allows the continuous circulation of the influent and effluent as a whole. On the basis of realizing water storage and water withdrawal cycle by using the pure water machine of the invention, all processes can be sterilized and disinfected by ultraviolet light, thereby ensuring the safety of drinking water in product use.

The above are only the preferred embodiments of the present invention, and are not intended to limit the scope of the invention, and the equivalent structure or equivalent process transformations made by the description of the present invention and the drawings are directly or indirectly applied to other related technical fields. The same is included in the scope of patent protection of the present invention.
